Description
FIELD OF THE INVENTION
[0001] A method or device designed to retain, attach and seal
thermoplastic composite material structures in a manner that
ensures weather tightness, structural integrity, and ruggedized
capability of the installation.
BACKGROUND OF THE INVENTION
[0002] U.S. Pat. No. 5,182,155 relates to a radome structure
providing high ballistic protection with low signal loss. The
radome has a composite wall structure including alternating layers
of polyethylene fiber laminating material which provides high
ballistic protection with low signal loss and fiberglass honeycomb
core material.
[0003] U.S. Pat. No. 7,560,400 relates to a radome comprising
flexible composite fabric material including polyester-polyacrylate
fibers in a flexible resin matrix material. This reduces radio
frequency transmission losses while at the same time providing high
strength.
[0004] U.S. Pat. No. 7,671,801 relates to an electronically scanned
ray that includes a plurality of armor segments interspersed
between a plurality of transmit/receive integrated microwave
modules, and a clamping element compressing the armor segments.
Such an armor facilitates a smaller footprint than a radome.
[0005] U.S. Pat. No. 7,681,485 relates to a laminated, optically
transparent, ballistic resistant structure having a first
transparent layer, a second transparent layer of ceramic tiles
spread across the first layer, and a third transparent layer. The
first and third layers are bonded to opposite sides of the second
layer by transparent adhesive.
[0006] U.S. Pat. No. 7,688,278 relates to a ballistic protective
radome consisting of longitudinal layer members densely packed in a
uniform array forming a main protective layer. The layer members
are electrically isolated such that a continuous gap is formed in
the main protective layer. The layer members are made of mechanical
energy absorbing and high tensile strength materials. The surface
of the layer members is electrically conducting.
[0007] U.S. Pat. No. 8,054,239 relates to a honeycomb-backed
armored radome. The radome is configured to extend over an opening
of an antenna and includes a rigid layer underlying a
ballistic-resistant layer. The rigid layer includes a honeycomb
based material having a plurality of holes that extend transversely
to the surface of the ballistic resistant layer.
[0008] U.S. Pat. No. 8,368,610 relates to a shaped ballistic radome
that comprises a system for shielding transmission devices for
ballistic deflection and protection of antenna equipment.
[0009] U.S. Pat. No. 8,599,095 relates to a broad band ballistic
resistant radome. The invention relates to a radome cover for a RF
sensor that comprises a first and second ballistic layer each
having a ceramic layer. The two ballistic layers are sandwiched
between at least two matching layers and the matching layers are
impedance matched to the ceramic layers. The radome cover provides
ballistic protection for the RF sensor.
[0010] U.S. Pat. No. 9,385,423 relates to a protective ballistic
radome for a satellite antenna which can turn about an axis of
rotation and has a circular support in the form of a ring. The
walls have their lower ends inserted into an annular groove of the
circular support to form a ballistic wall in the form of a tube of
a circular section having the same axis of revolution about the
satellite antenna.
[0011] U.S. Pat. No. 9,669,568 relates to a process for producing a
three-dimensionally shaped article comprising: providing a
structure containing a plurality of films or tapes of
uni-directionally oriented polymer and forming the structure into a
three-dimensionally shaped article by applying a force under the
melting point of the oriented polymer. Shaped articles thus
obtained are suitable for use as anti-ballistic articles.
[0012] U.S. Patent publication 2010/0166994 relates to a curved
armor product. The armor product is produced by a filament winding
process in which a plurality of reinforcing elements in the form of
fibers or tapes are impregnated with a polymer matrix and wound
onto a mandrel. The polymer matrix comprises a solution or
dispersion of a polymer in a carrier fluid which is partly
evaporated during winding. The armor product comprises a high
amount of reinforcing elements with respect to the total mass of
the product.
[0013] U.S. Patent publication 2011/0159233 relates to a process
for manufacturing a curved product comprising positioning a
plurality of drawn polymeric reinforcing elements onto a mandrel,
adhering at least part of the elements to each other, and removing
the product from the mandrel. The curved article is preferably an
armor article which has good anti-ballistic properties and is
substantially free from wrinkles.
[0014] U.S. Patent Publication 2014/0000796 relates to a curved
armor product produced by a filament winding process in which a
plurality of the reinforcing elements are in the form of fibers or
tapes that are impregnated with a polymer matrix and wound onto a
mandrel. The polymer matrix comprises a solution or dispersion of a
polymer in a carrier fluid which is partly evaporated during or
after winding. The armor product comprises a high amount of
reinforcing elements with respect to the total mass of the
product.
[0015] U.S. Patent Publication 2014/0078016 relates to a material
for radomes. The material comprises at least one laminate component
containing polymeric fibers wherein the material has a loss tangent
of less than 8.times.10.sup.-3 radians as measured at a frequency
chosen from the group of frequencies consisting of 1.8 GHz; 3.9
GHz; 10 GHz; 39.5 GHz; and 72 GHz.
[0016] U.S. Patent Publication 2015/0033936 relates to composite
panel comprising at least one layer containing at least one tape
comprising a thermoplastic polymer selected from the group
consisting of polyolefins, polyesters, polyvinyl alcohols,
polyacrylonitriles, polyamides or polyketone, and an adhesive in
contact with said layer, wherein the adhesive is a plastomer
wherein said plastomer is a random copolymer of ethylene or
propylene, the tape comprises an ultra-high molecular weight
polyethylene. The composite panel is used in a ballistic resistant
article.
[0017] U.S. Patent Publication 2015/0222011 relates to composite
radome wall structures that exhibit both antiballistic and radar
transparency properties and include an antiballistic internal
solid, void-free core and external antireflective (A) surface
layers which sandwich the core. The antiballistic core can be a
compressed stack of angularly biased unidirectional polyethylene
monolayers formed of tapes and/or fibers. Face sheets and/or one or
more impedance matching layers may optionally be positioned between
the antiballistic core.
[0018] U.S. Patent Publication 2016/0178327 relates to ballistic
resistant sheets and articles such as curved ballistic resistant
armor and helmets. The ballistic resistant sheets are a multi-layer
monolayer construction including a core layer having first
unidirectional oriented reinforcing fibers and an elastomeric
material sandwiched between the face layers.
[0019] U.S. Patent Publication 2016/0380345 relates to composite
anti-ballistic radome walls that have radar transparency properties
and include an anti-ballistic internal solid, void-free core and
external antireflective surface layers which sandwich the core.
